Anotations

Scope note:

The second of three divisions of the Cenozoic Era encompassing the interval between 23 million and 2.6 million years ago and including the Miocene and the Pliocene epochs, preceded by the Paleogene period. Marine and terrestrial life of this time were more closely related to each other than to those of the Paleogene. The Neogene and Paleogene periods are new additions to the geologic time scale and together represent what was formerly referred to as the Tertiary period.
